PURPOSE: To establish a protocol for image-guided minimally invasive

surgical access to the temporomandibular joint (TMJ). MATERIALS AND METHODS:

This study involved 2 patients with TMJ pain and mandibular motion

dysfunction. Axial magnetic resonance imaging (MRI) of the TMJ was obtained

and loaded into an intra-operative navigation system to guide joint space

injection. With a navigated syringe, 1 mL synvisc Hylan G-F 20 was directly

injected into the superior and inferior joint spaces under navigation

guidance. RESULTS: With the assistance of an intraoperative navigational

system, the TMJ MRI images were visualized in 3 dimensions and enabled

guiding a needle into the superior and inferior joint spaces for therapeutic

injection. The treatment outcome for both patients was satisfactory with

improvement in pain score and mandibular motion.

CONCLUSIONS: A protocol for image-guided minimally invasive surgical access

to the TMJ was established. This could provide the technical basis for

evaluation of accurate joint space intervention as a form of treatment of

appropriate TMJ disorders.
